High Pressure Viscometer 440

SPCL440 High Pressure Research Sensor

Our industry leading viscosity technology is based on a simple and reliable electromagnetic concept. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyzes the piston’s two-way travel time to measure absolute viscosity. Built-in temperature detector (RTD) senses the actual temperature in the sampling chamber.

Fluid flows through ¼”OD, 0.086” tube for measurement. Fluid may be measured under low flow or static conditions. System measures viscosity, temperature and temperature compensated viscosity. It provides data via RS-232, RS-485 or 4-20 mA signal.

The model SPL440 installs into a high pressure pump through type system. Both ends mate to HiP HF4 fittings with a 9/16-28 thread. The SPL440 is rated for continuous operation up to 20,000 psi and is static tested to 30,000 psi.
